DSC04902

The middle mouse button, an often overlooked and under-appreciated button on our gaming and office mice. The primary use of a middle mouse button is to endlessly scroll while we game, procrastinate, and work – but what do you do if the middle mouse button is not working?

Just like uses for the middle mouse button, there are a few causes that can prevent your middle button, middle clicker, or infinite scroll wheel from working. The issues can be from generic hardware problems, corrupted driver installations, and sometimes even your registry settings causing problems.

Is your middle mouse button not working? Don’t worry, in this article we are going to run through common issues and some fixes!

Preliminary Checks

Now it is highly likely you have already tried disconnecting and reconnecting your mouse, if not, please do as this can often fix the middle mouse button not working problem. Now if this has done nothing, you can try plugging your mouse into another computer/ laptop to see if the middle mouse button works elsewhere. If the middle button works while connected to the other PC, the problem is likely to be with your computer or a software issue rather than a hardware problem for the mouse.

If, however, the middle mouse button is still not working, it is likely to be a hardware issue. If you have a modular mouse or have opened up the shell before, you can take a look inside but it is best to run through the alternative steps below to try and fix the problem before finally sending your mouse back to the manufacturer.

Fix 1: Run Windows Hardware Troubleshooter

It has never been easier to troubleshoot a hardware issue than with Windows 10. It is worth trying this as another quick fix before we get into driver updates and registry files.

  1. Go to Control Panel by typing it in your Windows search bar and pressing Enter
  2. Open Hardware and Sound
  3. Open Devices and Printers 
  4. Locate your mouse, right-click on the icon and select Troubleshoot 

Fix 2: Update your Mouses Drivers

Now there will be many of you like me that have a mouse that requires zero drivers to work and is simply plug and play. That being said, there are also plenty of mice that require driver updates.

Do not download tools like “DriverEasy” as programs like this are never really that helpful as they scan your devices for drivers but will try and get you to pay for a quicker download. There is also no need for programs like this, you can simply search manually on the internet by using the name of your mouse followed by “drivers”.

When searching manually, you will come across your mouse manufacturers page, follow this and simply download the latest driver shown and then run the installer! If the driver update doesn’t require you to restart your PC, you should do so anyway and check to see if the issue has been fixed.

Fix 3: Change The Registry Settings

It may seem strange but if your middle mouse button isn’t working, it could be your registry settings.

  1. Go to Registry Editor by typing it in your Windows search bar
  2. When opening Registry Editor it will ask permission to make changes to your PC, click Yes
  3. Double click HKEY_CURRENT_USER, the second folder on the list, then Control Panel, then Desktop 
  4. Now in the Desktop folder, scroll down until you find WheelScrollLines (it’s in alphabetical order) and right-click.
  5. Now you have right-clicked on WheelScrollLines, click on Modify and make sure the Value Data is set to 3

Middle Mouse Button Still Not Working?

If everything above still hasn’t fixed the middle mouse button not working issue, the next step is to get in touch with the retailer that sold you the mouse. Alternatively, if the mouse is no longer in warranty it is worth contacting the mouse’s manufacturer to see if you can get the mouse repaired or replaced.

If nothing has worked and your mouse is rather old it could be worth buying yourself a new gaming mouse. Whether it’s wired or wireless, WePC has tried and tested the best of the best to help you find your next mouse.
